| 摘 要： | 针对目前地震水氡模拟观测操作繁琐、干扰因素多等现状,引入新型水氡观测仪进行检测并与FD-125测氡仪开展对比试验研究。两款水氡观测仪在地震监测氡观测仪检测平台标准氡室校准,并依托九江地震台相同水样和环境下开展对比测量表明,在静置时间为1 h前提下,新型水氡观测仪重复性、相对误差、相对固有误差、固有本底符合技术要求,与FD-125测氡仪对比测量数据的一致性较好,但灵敏度指标有待提升。该仪器整体设计基本满足地震模拟水氡测量发展需求,可减少人工操作带来的测量误差,提升测量效率和数据质量。

| Abstract: | The simulated observation of water radon in China is cumbersome and has many interference factors.To overcome this drawback,a novel radon detector instrument was introduced in this paper,and a comparative experimental study was carried out with the FD-125 radon detector.The two water radon detectors were calibrated in the standard radon chamber of the emanometer measurement platform for earthquake monitoring,and a comparative measurement with the same water samples and environment was carried out at Jiujiang seismic station.The results show that the repeatability,relative error,relative inherent error,and inherent background of the novel radon detector can meet the technical requirements with a standing time of 1 h.The observation data has good consistency with those of FD-125 radon detector,but the sensitivity index needs to be improved.The overall design of the proposed instrument can basically meet the development needs of analog water radon observation and reduce the measurement error caused by manual operation,thus improving the measurement efficiency and data quality. |
